摘要
针对无线Mesh网络,提出一种支持多路径路由的先验式多树路由协议(Proactive Multi-Tree Routing Protocol,PMTRP).通过建立先验式多树及比较积累传播时链路度量(Accumulated Airtime Link Metric,AALM),来实现在数据传输过程中的路由选择.在NS-3网络仿真环境下实现PMTRP路由协议,将其与IEEE802.11s协议中缺省路由协议HWMP进行对比,证明PMTRP路由协议拥有更好的网络性能.
In view of wireless mess networks, rate, a new routing protocol of PMTRP （Proactive Multi-Tree Routing Protocol） that supports multi-path routing is proposed in this paper. By setting up proactive multi-tree and comparing AALM （Accumulated Airtime Link Metric）, it does route selection in the process of data transmission. By implementing the PMTRP routing protocol on NS-3 network simulator, the comparing between PMTRP routing protocol and the default HWMP routing protocol in IEEE 802. lls proves that PMTRP has better network performance.
